Xorg crashed with SIGSEGV when switching from other virtual terminal

[Dimitar Krasimirov Boichev]

After the upgrade to 9.04 most of the times I switch to other TTY it's ok ..... until I try to go back to TTY7 ( where is the first X ) When I try sometimes it's ok but this is rare. Most times it crashes.

This bug report was filed against an old version of Ubuntu.
Can you confirm whether this is still an issue in natty?

If you don't mind, it would be very helpful if you could update the bug
report in launchpad to 'Fix Released' if it is no longer an issue for
you, or if it is still occurring under natty, please tag the bug 'natty'
so it's easier for us to track.
